Power Bank Working Principle

Many people think that there is just one battery in the power bank, and the battery is just charged, and then the same battery charges our phone. But this does not happen. The power bank has very complex equipment. The circuits that are installed inside it manage how many volts of current to send, because if we charge the mobile battery, not with 4.2 volts but any other volt, then the battery can be hot, and this battery Is also not good for life.

The power bank consists of very complex circuits, which manage to discharge from current volts, and the input is also from a fixed voltage. That is why the power banks of the branded company come at high prices because very complex electrical components are used in it. If you want to get a good power bank, then definitely read the last paragraph of this article.

It is first decided how many mAh batteries are to be installed, and the outside design is made with plastic, then the battery is fitted inside it, and the batteries are joined with the circuit. So that the charging can be done at only one voltage and then the same circuits are connected to the USB ports so that the battery can be charged and the LED lights are provided to display the percentage of charging left.

After that, the plastic box is completely sealed, and the company logo is applied on the top, if there is a power bank of Samsung, then the Samsung logo is put, if it is from another brand, then The brand logo is placed on it, and the power bank is fully prepared.

The output of 3.7 volts comes from the power bank, and the battery of the phone which is charged at 4.2 volts, that’s why there is a voltage downgrade, due to which we do not get 100% energy of a power bank. There is no such thing in the world from which we can get 100% energy. For example, when charging the phone, the power bank is a little bit hot, and that energy comes from where that energy is, from the capacitance of the power bank. That is why no power bank gives 100% energy.

A 10,000 mah power bank will be able to charge a 5,000 full charge once and about 80% the second time (10,000 × 3.7 / 4.2 = 8,809). Such a capacitance is achieved by decreasing the voltage of a 10,000 mah power bank.
